The PENFED Promise Visa Credit Card is a no-frills credit card. Its most notable feature is a lack of frees. It has no fees for cash advances, foreign transactions, late payments, or even returned payments. It also offers virtually no rewards and has no 0% introductory APR on purchases or balance transfers. It does offer a $100 statement credit, but requires you to spend $1,500 on the card in the first 90 days to qualify.
In short, there are much better credit cards available today.
